Appium ARC returns immediately after it's execution

Following official documentation and tutorials I got stuck with arc execution.

I have setup everything and it is right now oppening the activity settings of the android emulator. I'm trying to input a scroll to Google item, however the command arc returns after its execution without entering on 'interactive mode' ( not sure how it's called) don't giving the opportunity to enter the following commands as scroll_to("Google")

I'm running appium server and it is ok and working as expected.

My appium.txt is:

[caps]
  platformName = 'Android'
  appActivity  = '.Settings'
  appPackage   = 'com.android.settings'
  deviceName   = 'emulator-5554'
[appium_lib]
  sauce_username   = false
  sauce_access_key = false

This link doesn't mention anything about it. [http://ift.tt/2xnOF4N]

Thank you.
